BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 783,187, dated February 21, 1905.

Application filed February 6, 1904. Serial No. 192%12.

To fI/ZZ 1071/0772 it may concern:

Be it known that I, FRANK M. FOOTE, a citizen of the United States, residing at Marshall, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Ball-Bearings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in ball-bearings for vehicles; and the object of the invention is to produce adevice of this character whereby all of/the perpendicular weight on the operative parts is dispensed with and in which I provide adouble-faced cup instead of cones, whereby the axle-box may be kept true while running on the axle.

My invention consists in various details of construction and in arrangements of parts, which will he hereinafter fully described and then specifically defined in the appended claims.

Hy invention is illustrated in the accompanying drawings, which, with the characters of reference marked thereon, form a part of this application, and in which- Figure 1. is a central longitudinal section through an axle-box and attachments. Fig. 2 is a detail perspective view of the threaded cap which lits over the axle-box. Fig. 3 is a sectional view through a bearing-cup. Fig. 4c is a plan view-of a washer. Fig. 5 is an end view of my invention applied to an axle and axle-box. Fig. 6 is a sectional view through a threaded nut adapted to lit within the cap shown in Fig. 2.

Reference now being had to the details of the.

drawings by letters and numerals, A designates an axle of the ordinary construction, and B an axle-box having a threaded portion about its outer circumference adjacent to one/end and over which a shell D, having a contracted inner end interiorly threaded, is adapted to be fitted. Said shell has a series of internal threads adjacent to its outer end, and C designates an axle-nut which has a shoulder K, the

inner face, forms a bearing-surface for the outer series of balls, while its circumference is threaded and adapted to be screwed into the end of said shell. Suitable indentures 3, one of which is shown in Fig. 8 of the drawings, are provided in the cup H, whereby a tool may be employed to screw said cup within the shell.

G designates a washer having diametrically opposite lugs 2 projecting therefrom, which are adapted to engage in the recesses 2, formed at positions diametrically opposite in the inner face of the outer threaded end of the shell. Said washer is provided to contact with the outer face of the cup H and when the lugs are in engagement with said recesses will be prevented from rotation. A retaining-nut H is provided, which has a threaded circumference and is adapted to be screwed into the outer end of the shell D and against said Washer, and in order to afford means whereby said nut may be adjusted to the wheel indentures 3, one of which is shown in Fig. 6, areprovided for the reception of any tool, whereby the nut may be conveniently turned. The end of the nut projects from registering apertures in said cup H" and nut H and is adapted to receive a wrench for the purpose of applying the nut to the end of the axle.

From the foregoing it will be observed that by the provision of my improved apparatus, in which a double-faced cup is used instead of cones, and arrangements of parts the axlebox will be caused to run true upon the axle and hammering of the parts is prevented. Y It will be noticed that the element 0 is threaded into-and covers the outer end of the axle and that it also has integral with it the concave ball-races. Said parts therefore form a combined cap-nut and ball-race and the end of the nut serves as a wrench-hold.

. While I have shown a particular construction of apparatus embodying the features of my vehicle ball-bearing axlenut, it will be understood that I may make alterations in the detailed construction of the same Without in any way departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. A ball-bearing comprising a cap-nut for an axle end having integral therewith two ilOlllgaVe ball-receiving faces and a wrenchio 2. A ball-bearing attachment for the ordinary axle comprising a cap-nut adapted to be threaded onto the axle end and having integral therewith a Wrench-hold and outer and inner concave ball-receiving faces.

3. In combination with the commercial axle and axle-box threaded at their outer ends,-a

cap-nut having integral therewith a wrenchhold and two concave ball-receiving faces and threaded to the axle, balls in said faces, means to engage the balls at opposite sides of the aforesaid faces, and a shell covering the balls and threaded to the axle-box.

4. In combination with a commercial carriage-axle and axle-box, a ball-bearing at one end only thereof, said bearing comprising an FRANK M. FOOTE.
